Happy Nerding 3XVCA Black future-sound-systems You may regard the A-138s3XVCA offers three high class amplifier circuits with linear characteristic. Thanks to AC DC compatibility, a very low noise floor and basically no distortion, the module is not only a great partner for control voltages, but audio material as well. Besides a signal input and output, each VCA has its own CV input. The dual potentiometers regulate levels and bipolar CV attenuation values of all amplifiers. Using these rather unusual, yet very practical
